Do You Need a Permit to Renovate a Kitchen or Bathroom in Montreal?
Updated: Sep 28
Updated September 2026
If you’re planning a kitchen or bathroom renovation in Montreal, one of the first questions to answer is whether your project requires a renovation permit.
The short answer is: not always.
According to the City of Montréal, cosmetic work such as replacing cabinets, countertops, flooring, a sink or a bathtub generally does not require a renovation permit. However, a permit is required for certain larger renovations, including work that affects walls or foundations, modifies the structure, increases floor area, or changes the dimensions, division or use of rooms.

The exact requirements can also depend on the borough, building type and scope of work. Montréal
Do You Need a Permit to Renovate a Kitchen in Montreal?
For a straightforward kitchen update, you may not need a municipal renovation permit.
The City of Montréal specifically lists the following as examples of work that generally does not require one:
Replacing kitchen cabinets
Replacing countertops
Changing flooring
Painting
Replacing a sink Montréal
For example, if you're replacing an existing kitchen with new cabinetry, stone countertops, flooring and fixtures while maintaining essentially the same room configuration, the project may fall under minor renovation work.
The situation changes when the renovation goes beyond finishes.
If your kitchen design involves removing or modifying walls, changing the dimensions or division of rooms, affecting the structure or increasing the floor area, a renovation permit may be required. Montréal
This is particularly relevant in Montreal homes where homeowners want to open a kitchen to an adjacent dining or living space.
Do You Need a Permit to Renovate a Bathroom in Montreal?
The same general principle applies to bathrooms.
Replacing a bathtub, sink, flooring, counters or other finishes generally does not require a municipal renovation permit on its own. Montréal
However, a more substantial bathroom redesign may require one if the project modifies walls, affects the building's structure or changes the room's dimensions, division or use. Montréal
This is why two bathroom renovations with similar finishes can have completely different permit requirements: the determining factor isn't how luxurious the renovation is, but what is actually being changed.
Do You Need a Permit to Remove a Wall in Montreal?
This is where homeowners should pay particular attention.
The City states that a permit is required for work affecting walls or foundations or changing the dimensions, division or use of rooms. If work affects the building's structure, structural plans signed and sealed by an engineer may also be required. Montréal
For example, transforming a traditional closed kitchen into a large open kitchen and dining area can therefore have different requirements from simply replacing the existing kitchen.
Determining this during the design phase can prevent permit requirements from being discovered only after construction drawings, cabinetry or contractor schedules have already been finalized.
What About Plumbing and Electrical Work?
There is an important distinction here.
The City of Montréal does not issue permits for plumbing, electrical, or electric or gas heating work. However, the work must still comply with applicable provincial regulations. The City specifically directs homeowners to the Régie du bâtiment du Québec for questions concerning those requirements. Montréal
Quebec also regulates construction contractors and specific categories of work. For example, electrical construction work is reserved to appropriately licensed contractors, while specialized plumbing and electrical licensing falls under Quebec's provincial framework. Régie du bâtiment du Québec
In other words, “no City renovation permit required” does not mean the work is unregulated.
Does Your Montreal Borough Matter?
Yes.
Montreal's requirements can vary according to the type of work, type and use of building, and the borough in which the property is located. Montréal
A renovation in Ville-Marie, Outremont, Plateau-Mont-Royal or NDG should therefore be evaluated according to the requirements applicable to that particular property and borough.
Westmount Heritage properties and areas subject to specific architectural standards can involve additional considerations as well. Montréal
What Documents Can Be Required for a Montreal Renovation Permit?
Depending on the project, the City may require documentation including:
A certificate of location
Building specifications
A cost estimate
Plans showing the proposed work
Professional-quality scaled plans in applicable cases
Engineer-signed structural plans when structural work is involved
Condominium projects can also require authorization from owners or a resolution from the condominium syndicate, depending on the situation. Montréal
This is one reason proper planning and technical drawings can become an important part of a larger kitchen or bathroom renovation.
How Much Does a Montreal Renovation Permit Cost?
As of the City's February 2026 update, permit application processing fees are calculated at $9.80 per $1,000 of projected work.
The minimum listed fee is $167.40 for a strictly residential building and $491.70 for a commercial, industrial, institutional or mixed-use building. Additional fees can apply to buildings or areas with historic value or specific architectural standards. Montréal
Because municipal fees and regulations can change, homeowners should verify the current requirements with the City before beginning a project.
